Summary:
Scientists at the Howard Hughes Medical Institute in Virginia have successfully mapped the circuitry in a small region of a fruit fly brain. It is a small but important step, according to the researchers, in gaining a better understanding of how the much larger and more sophisticated human brain processes information. Rob Muir has more.

Does Social Engagement Have a Genetic Root?

FORA.tv (May 13, 2013) — Does Social Engagement Have a Genetic Root? California Academy of Sciences - California Academy of Sciences Innovation is critical for both individual and evolutionary success, but creative disruption requires taking risks. New research marrying the theory and methods of economics to cutting-edge neuroscience techniques - an emerging field known as NeuroEconomics - is making new discoveries about the biological processes that motivate us to take risks and create new solutions to unforeseen challenges. Dr. Platt will describe how the brain overcomes uncertainty to explore novel alternatives and create new knowledge. Parallel findings from humans, monkeys, rodents, and worms indicate that a common suite of underlying mechanisms has evolved to control the desire to explore. At one extreme, neuropsychiatric disorders like attention-deficit hyperactivity disorder, obsessive-compulsive disorder, and addiction, may arise from dysfunctional control of exploration. At the other, uniquely human faculties of creativity and technological innovation may reflect elaboration of this shared biological heritage controlling our desire to explore.

Dragonfly Backpacks to Probe Secrets of the Brain

Reuters (Nov. 8, 2013) — Scientists in the US are planning to map the brain activity of the dragonfly as it hunts, using a specially built backpack to transmit electrical signals from the insect's active neurons to a computer. The researchers believe that, if successful, their experiments could shed lite on how the human brain functions and how degenerative diseases like Parkinson's and Alzheimer's develop. Rob Muir reports.

The Acai Berry Takes Brazil by Storm

AFP (July 7, 2012) — Very popular in Brazil, the acai has invaded the US, Japan and Australia. This black berry, cultivated on the edges of the Amazon, is already known for its exceptional nutritional qualities even though lab research on the fruit is still in its early days. Nevertheless, the fruit's virtues are often overlooked in favor of financial gain.
